This is a 2D side scrolling city builder. So it's all about waiting.
It's a nice idea but its ruined by monetisation. The game already has a significant cash shop but on top of that there's adds for everything. This would be ok if they were optional but they are not. The game has been specifically designed to force you to watch adds to progress.
For example your warehouse is so tiny that you can barely store anything so you will eventually reach a point where the only way of storing things that don't fit in is to watch 30 second adds. You can upgrade your warehouse which helps for a cycle or two then you're back to watching adds. You eventually end up in a cycle of not being able to build or upgrade anything because you haven't got enough resources because those resources won't fit in the tiny warehouse.
This type of forced add watching would be ok if that was it, but the game also has the usual overpriced mobile game cash shop on top.
The controls are also very janky in some parts which makes the game frustrating. The gacha is the usual abysmal rates too.
It's a fun side game for a few hours until you reach the 30second add paywalls.
